Answer:
so the scale factor of the image is

Explanation:
We have to find the scale factor of figure A'B'C'D' which is the dilated image of quadrilateral ABCD.
Now we choose a line segment AB and compare it with line segment A'B'.
Since length of AB = 4 units
and length of A'B' = 1 units
So ratio of AB and A'B' =

so the scale factor of the image is
